Area Forecast Discussion National Weather Service Austin/San Antonio TX 638 AM CDT Sun May 19 2019 .AVIATION... A mix of IFR/MVFR ceilings and visibilities at the terminals will linger through mid- morning as a soupy 70+ degree dew point airmass sits across the terminals today. Brief drops to LIFR will be possible. Expect heating to gradually allow ceilings to lift to high end MVFR mid to late morning with improvement to VFR by this afternoon. Ongoing TSRA southeast of DRT will continue to move southeast, remaining outside of the vicinity of the Austin and San Antonio terminals. Otherwise, expect light and variable winds this morning to become southeasterly near 10 knots by midday with further strengthening to near 15 knots by the end of the 30 hour TAF period for AUS and SAT. Redevelopment of IFR ceilings overnight may be short-lived as these winds increase, with rises back to MVFR possible by 12Z Monday. && .PREV DISCUSSION... /ISSUED 414 AM CDT Sun May 19 2019/ SHORT TERM (Today through Monday)... Early morning surface analysis revealed the dryline had retreated to a Mineral Wells to Rocksprings to Langtry line. With the KDFX VAD wind profiler showing south to southeast winds around 20 knots through 3kft AGL and nocturnal cooling of air north of this boundary, current expectations are for the dryline to nudge a bit farther to the north through the remainder of the pre-dawn hours. South of the dry line, dewpoints surging into the mid to upper 70s have resulted in patchy fog development across most of South Central Texas. Deep moist convergence within the vicinity of the dryline is allowing for thunderstorm development occur across Kinney and Val Verde Counties early this morning. SPC Mesoanalysis for this area shows some very high SBCAPE values in the 4000-5000 J/kg range as well as some modest mid-level cold air advection associated with the passage of the large trough over the Central Plains. Both of these factors, combined with effective bulk shear in excess of 40 knots, will result in a risk for an isolated severe thunderstorm or two for areas along the Rio Grande early this morning. One such thunderstorm was currently ongoing as of this writing just southeast of Del Rio. Large hail appears to be the main threat, but a damaging wind threat also cannot be ruled out. Farther east, patchy fog is expected to lift mid to late morning with onset of daytime heating. After a warm start this morning with several locations again possibly tying or setting record high minimum temperatures today (more information in the climate section below), convergence along the dryline may allow for a secondary round of thunderstorms to develop across Val Verde County this afternoon. The rest of the region is expected to remain dry today with highs in the upper 80s to mid 90s under partly cloudy skies. Southeast flow persisting across the region tonight and associated warm air advection may allow for a few streamer showers to develop for areas roughly east of Highway 281 by sunrise Monday with another round of patchy fog possible. Best chances for this fog appear to be across the Coastal Plains and into the Interstate 25 corridor where winds are forecast to be lighter. Very warm overnight lows in the low to mid 70s are expected again tonight. On Monday, a closed low off the California coast early this morning swings into the Four Corners region and amplifies the southwest flow aloft over the Southern Plains. Height falls associated with this system are four standard deviations below normal for this time of year and this will only help to induce rapid lee cyclogenesis along the Front Range of the Rockies. While the overall trajectory of this system places the best dynamics over portions of the Texas Panhandle, Oklahoma, and Kansas, the strength of this system will result in increasing winds across South Central Texas during the day on Monday with winds increasing into the 15-25 MPH range across central and eastern portions of the region and 20-30 MPH along the Rio Grande. This will also allow for a few streamer showers to linger during the day across much of the region with an isolated thunderstorm or two possible along the dryline in Val Verde County during the afternoon. Highs on Monday are forecast to range from the mid 80s across the Hill Country to upper 90s in the Rio Grande Plains. LONG TERM (Monday Night through Saturday)... By Monday night, the closed low becomes an open wave as it swings into Colorado and pushes the dryline eastward. This may allow for another broken line of showers and thunderstorms to develop and push into the region late Monday night and Tuesday morning, with streamer showers developing ahead of the line Monday night. As we saw this weekend, the strength of the cap will play a big role in how far south these storms will be able to extend and presently expect best rain chances to materialize for areas of north Interstate 10. Given the wind energy associated with this system, a strong wind gust or two may be possible with these storms. Expect this system to push east of the region by Tuesday evening. Generally dry conditions are expected through the remainder of the forecast as upper ridging spreads into the region with temperatures near to above normal as a result. CLIMATE... Above normal overnight temperatures are forecast to continue for the next few days across South Central Texas and many locations may tie or set new record high minimum temperatures.
